Once installed, import thematplotliblibrary. You’ll likely also want to import thepyplotsub-library, which is what you’ll generally be using to generate your charts and plots when using matplotlib. In[1]:importmatplotlibimportmatplotlib.pyplotasplt Now to create and display a simple chart, we...
To add a simple linear trendline to your Matplotlib plot, you can use NumPy for linear regression. Here’s how you can do it: import numpy as np import matplotlib.pyplot as plt # Sample data x = np.array([1, 2, 3, 4, 5]) y = np.array([2, 3, 5, 7, 11]) # Create a ...
In this example, we open an image namednew_york_city.jpgand save it asnew_york_city.png. This is particularly useful when you need to convert images between different formats. Example: Save an Image to a Directory with Pillow Library Let’s see how to save an image to a specific direct...

Often during the execution of our Matplotlib Program, we will need to update our plot from time to time. Common examples of this are when we need to do plotting in Real-time. In such cases the Plot must be updated very frequently. But how do we do so? There are two methods that you...
import matplotlib.pyplot as plt def basic_plot(): # The number of x and y list elements should be the same # The x list is the X-axis data x=[1,2,3] # The y-list is the Y-axis data y=[6,8,7] # call the plot function to draw the figure. ...

To create a basic 3D cone plot, you’ll use Matplotlibmplot3dtoolkit: import numpy as np import matplotlib.pyplot as plt from mpl_toolkits.mplot3d import Axes3D fig = plt.figure(figsize=(10, 8)) ax = fig.add_subplot(111, projection='3d') ...
Clear a Plot in Matplotlib with clf() In order to clear the currently drawn Graph/Chart, we can use theclf()function (Which I believe stands for “clear figure“). An example of how it may be used it as follows: 1 2 3 4
To introduce a cursor in our plot, we first have to define all its properties; to do that, we exploit the functionCursor,from thematplotlib.widgetpackage. The function takes as input the axes in which we want to display the cursor (“ax” in this case) and other properties of the curso...
